Ecological purification treatment method for hardened river channel water body

Abstract

The invention discloses an ecological purification treatment method for hardened river channel water body, belonging to the technical field of river channel water treatment. The method comprises the following steps: previous preparation: building an ecological purifying device which is to be arranged on a riverbed of a hardened river channel; planting: planting aquatic plants on the obtained ecological purifying device; arrangement: arranging the ecological purifying device on which the aquatic plants are planted on the riverbed of the hardened river channel and suspending the ecological purifying device relatively to the riverbed, wherein the growing aquatic plants are used for ecological purification of the water body of the hardened channel. The method disclosed by the invention can be used for treating the water of the river channel by a biological way as well as recovering and improving the self-purification capability of the water body; the sparsity is controllable; an excellent natural landscape effect can be achieved, and an ecological purification effect of the water body can be guaranteed as well; the riverbed is not raised and no influences are caused to flood discharge as well; the method is beneficial to improving the mechanical stability of a riparian zone and can be used for farthest reducing the into-river pollution load.

Description

technical field [0001] The invention belongs to the technical field of river course water quality treatment, and in particular relates to an ecological purification treatment method for hardened river course water. Background technique [0002] Due to the relative lag in the treatment of industrial sewage and domestic sewage in my country, coupled with the weak public awareness of environmental protection, a large amount of industrial and domestic sewage is frequently discharged directly into the river without treatment, resulting in the general deterioration of the water quality of the river. Concrete and mortar revetment are of positive significance for improving the flood control and anti-flood ability of urban rivers, but at the same time, they also aggravate the hardening of the river, which affects the natural connection between the upstream and downstream of the river and the ecosystems inside and outside the river, making it difficult for river plants to It can't eve...

Problems solved by technology

But there is following shortcoming: one, owing to being shown as bagged structure, thereby the sparse density when throwing in river course water body is difficult to grasp, adds that there is natural gradient in river course, if throwing in too densely, stacking effect then easily occurs, if throwing in too much If it is sparse, it will affect the ecological purification ability, and whether it is too dense or sparse, it will have an impact on the landscape effect; Thirdly, because the degradable woven mesh bag is difficult to attach to the slope of the river (the slope of the river bed), it tends to be dumped to the bottom of the river bed, so it is difficult to provide water for the river bank. Microbial communities and vegetation growth provide the desired eco-environmental conditions, but do nothing to improve the mechanical stability of the riparian zone
